GAS SAVER.

Application led March 10, 1925. Serial No.-14,541.

This invention relates to an improved automotive appliance frequently referred to as a gas saver, and it has more particular reference to a device of this class which serves to conduct oil and unconsumed fuel from the crank case to the carburetor.

It is of course a well known fact that fuel obtained from this source and introduced into the carburetor serves to save from onefourth to one-third of the gas.

In carrying out the present invention it has been our primary aim to generally improve upon a device of this class by providing one which is used in association with a transmission cover plate and which is provided with a flexible conduit leading from this cover plate to a hot air supply pipe such as is used in conjunction with a carburetor on a Ford type of automobile.

Numerous advantages and features of the specific construction employed will become apparent from the following description and drawing.

In the accompanying drawing forming a part of this application and in which like numerals are 4employed to designate like throughout the same:

Figure 1 is a side elevation of a portion of a motor such as is used in a Ford automobile showing the improved gas saving device in association therewith.

Figure 2 is a top plan view of the transmission cover plate forming an important detail of the invention.

Figure 3 is a centralV longitudinal section taken approximately upon the line 3-3 of Figure 2.

Figure 4L is an enlarged detail view taken substantially upon the plane of the line 4.-i of Figure 1.

Referring to the drawings, it will be seen that the reference character 1 designates generally a motor of the type used in Ford automobiles, the same embodying the customary crank case 2, transmission housing 3, intake and exhaust manifolds 4L and 5 respectively, and an appropriate carburetor 6 connected with the intake manifold. Also connected with the carburetor and cooperating with the exhaust manifold is a hot air conducting pipe 7 of conventional form, there being an appropriate valve 8 between the carburetor and pipe to control the intake of hot air derived from the exhaust manifold in the usual way. It is with this hot air supply pipe 7 that the present improvement is immediately connected.

As before intimated, the invention comprises essentially a transmission cover 9 which, instead of being constructed as usual, is provided on its under side with a vapor collecting pocket 10. It will be noted that the pocket inclines downwardly toward its intake end so that condensed fuel vapors will be drained back into the transmission casing. An opening 11 is formed at the discharge end of the pocket, and a pipe 12 is connected at its inner end to the cover plate so as to communicate with this opening. Detachably connected in any appropriate manner with the free end of the pipe 12 and the intermediate portion of the hot air pipe 7 is a flexible tube 13.

From the foregoing it will be obvious that under the suction produced by the engine all vapors and otherwise wasted gas will be collected upon the crank case and conducted through the pocket 10, pipe 12 and tube 13 into vthe carburetor to be mixed with the fuel mixture there ordinarily formed.- By

associating the tube 13 with the pipe 7 it is obvious that the vapors passing through the tube will be pre-heated before entering the carburetor.

Actual use of a device constructed strictly in accordance with the present invention has shown that it undoubtedly increases the efficiency of the motor. Not only does it save gasoline, but by relieving the crank case of the harmful, yet useful vapors, it constitutes an oil purifying device, by preventing such vapors from divesting the oil of useful constituents. It has been observed too, that the motor runs smooth, that carbon deposits are reducedand that the oil in the crank case is kept from freezing in cold weather. On

the other hand, in warm weather it permits a circulation which serves to cool the oil and by relieving back pressure it 1n turn keeps the engine from pumping oil, whereby to lieve doubtless been made apparent by the foregoing description and drawing. For this reason e more lengthy description is thought unnecessary.

Although the preferred embodiment of tbe invention has been shown and described, it is to be understood that minor changes ooiningr within the field of invention claimed may be resorted to if desired.

Having thus described the invention, what we claim as new is In combination, a transmission Cover having its intermediate portion raised to forni a pocket, a plate extending from the forward end of the pocket and inelining` downwardly and terminating below the lower end of the pocket, walls rising from the sides of the plate. and ixed to the cover, a pipe extending from the upper end of the pocket in the cover.

In testimony whereof we afix our signetures.
